I purchased this awesome lens, new, from my local camera store (Precision Camera in Austin TX; a Sigma authorized dealer) a couple of months ago. I intended it to be part of a gift for someone, but I pivoted and ended up getting them something else. I don't have use for the lens, but I do admire it. The F1.8 aperture looks amazing; no need to stop down IMHO.
FWIW, the autofocus on the TL2,CL, and SL3 is fast (camera and the lens's doing), and accurate (camera's responsibility). It really is a great zoom lens.
I have tested it on the aps-c (native for the lens) Leica TL2 and CL, and it works great on both. In addition, I took some shots with it on an SL3 (in APS-C mode) and it works amazing there too.
The filter size is e67, and I will include a UV filter for you.
In addition to the great lens, you will get a copy of my receipt and contact information for warranty support etc. Finally, you will get all the stuff that the lens comes with, including the hood, box, and a soft case. It will be as if you bought an open box from your camera store.
The pictures included in the listing that are not of the Sigma Lens, or its packaging, are ones I shot with your lens for some examples of how it shoots (F1.8 in all cases).
I will ship it free to you via USPS Priority Mail, but if you are in the Austin Texas area, you are welcome to pick it up in person.
